Couple of points.

First, it should be mentioned that forums such as this tend to attract a disproportionate number of problem posts vs. people who are completely satisfied. The average joe (non-enthusiast) doesn't seek out a place like this unless he needs some kind of help. So don't take what you read here as a representative sample. It isn't.

Second, I wouldn't fret over meager fuel savings over the life of the car just because it costs $2.20/gal right now. For one thing your "savings" due to higher fuel costs necessarily mean more money out of your pocket. It looks better on paper but is not good for your wallet, so be careful what you wish for. (I tend to wish for fuel prices on the higher side, but solely in hopes of reducing consumption/environmental impact through natural market forces.) Another thing about the $2.20 gas is that there's no guarantee you will be paying that amount in four years, one year, or even six months. The long-term trend is upward as global demand increases, not down.

Please don't get worked up by worrying about problems that you have yet to encounter. Take it from someone who knows, it's a sure-fire way to drive yourself nuts.
